This is a tool for HamSphere 4.0 Broadcasters. It utilizes a powerful 1.2 kilowatts Power Amplifier tuned for 48m as well as an Advertising Message function where the broadcaster can promote its broadcast in the DX Monitor window. In addition it includes a canned private message system such as "Thank you for report" etc which can be sent to listeners on air.
This plugin can be downloaded for free, but it only works with a BC account. The BC account costs 30 Euro +VAT per year. Please contact HamSphere Support if you interested in becoming a broadcaster on 48m.
